The dealership by me basically told me that anything I alter on the car that did not come with it from the factory can void the manufactures warranty (whether its problem or not). The dealership themselves who has the extended warranty also told me they will not void my warranty unless the part is the problem which they said they would gladly replace back to stock if needed but as we all know it's going to cost an arm and a leg. Lol.
That went for both my daily and my st3 model. They also said that if they install the part they would make sure it properly worked before releasing the vehicle to me.
The dealership I showed the fswerks short ram and the tech told me that would be an acceptable modification becuase it does not alter the location of the intake.
